The scale factor of dilation is 
.
<h3>What is scale factor?</h3>
When describing an enlargement you must state by how much the shape has been enlarged or reduced.
Area of triangle B =
= 0.5 x 2 x 3
= 3 units
Area of triangle A =
= 0.5 x 4 x 6
= 12 units
Scale factor =
=
= 
Hence, the scale factor of dilation is .

Step-by-step explanation:
Answer:
$7.34
Step-by-step explanation:
To compute sum of dollars that are not whole numbers. Using the sum of$5.89 and$1.45 as an illustration :
$5.89 + $1.45
Taking the whole numbers first:
$5 + $1 = $6
Take the sum of the decimals :
$0.89 + $0.45 = $1.34
Sum initial whole + whole of sum of decimal
$6 + $1 = $7
Remaining decimal : $1.34 - $1 = $0.34
$7 + $0.34 = $7.34
Answer:
a = 180° -73°
b = 73°
c = 180° -73°
Step-by-step explanation:
73° and b are vertical angles, so are congruent (equal).
a and c are equal to each other and each is a linear angle with 73°, so is the supplement of that angle. You could write the equation as ...
a + 73° = 180°
but I prefer to get to the heart of it. The values of a and c are the difference between 180° and 73°.
